142 NEW TRACKS IN NORTH AMERICA. 
Ocean, and the water seen about the centre is a shallow part 
_ of the harbour, which has to be crossed in boats. The harbour 
of Mazatlan is not a very good one, for it is exposed to the 
south-west gales in one part, and to the north-west in another, 
so that it depends much upon the prevalent winds what 
position is the best for anchorage. 
I left Mexico with considerable regret, for another month 
might have been well spent in travelling through different 
parts of Sonora, in visiting the coal-fields on the Upper Yaqui, 
and in examining the silver mines of Alamos. 
The greatest source of wealth possessed by Sonora is 
undoubtedly her mines. I visited many of them, although 
I did not reach Alamos; and shall therefore conclude this 
account of my trip by fairly stating as much of the reliable 
information I then collected as I think is of sufficient general 
interest.
